Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Could you tell me if nslookup works on server with the broken yum?
nslookup mirror.centos.org ipofyournameserver
if it replies.
I saw another post by you about the webserver reolving to 127.0.0.1 and am guessing if fault dns could have been the cause.
On the same token, what's the content of /etc/resolv.conf on that server with the faulty yum?
You also mentioned your boss uses a http proxy. Any chance you try setting yum to use the http proxy?
Almost running out of ideas, i would suggest you reinstall yum i.e: download the yum rpm to the server or extract it from a centOS dvd, rpm remove yum and then rpm install it back again.
and the output of yum.conf is:
# PUT YOUR REPOS HERE OR IN separate files named file.repo
# in /etc/yum.repos.d
and the output for /etc/yum/repos.d/Centos-Base.repo is:
# This file uses a new mirrorlist system developed by Lance Davis for CentOS.
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
